<h2>Detailed Description</h2>
<p>The QDesignerFormWindowManagerInterface class allows you to manipulate the collection of form windows in Qt Designer, and control Qt Designer's form editing actions.</p>
<p>QDesignerFormWindowManagerInterface is not intended to be instantiated directly. <i>Qt Designer</i> uses the form window manager to control the various form windows in its workspace. You can retrieve an interface to <i>Qt Designer</i>'s form window manager using the <a href="qdesignerformeditorinterface.html#formWindowManager">QDesignerFormEditorInterface::formWindowManager</a>() function. For example:</p>
<pre> QDesignerFormWindowManagerInterface *manager = 0;
 QDesignerFormWindowInterface *formWindow = 0;

 manager = formEditor-&gt;formWindowManager();
 formWindow = manager-&gt;formWindow(0);

 manager-&gt;setActiveFormWindow(formWindow);</pre>
<p>When implementing a custom widget plugin, a pointer to <i>Qt Designer</i>'s current <a href="qdesignerformeditorinterface.html">QDesignerFormEditorInterface</a> object (<tt>formEditor</tt> in the example above) is provided by the <a href="qdesignercustomwidgetinterface.html#initialize">QDesignerCustomWidgetInterface::initialize</a>() function's parameter. You must subclass the <a href="qdesignercustomwidgetinterface.html">QDesignerCustomWidgetInterface</a> to expose your plugin to Qt Designer.</p>
<p>The form window manager interface provides the <a href="qdesignerformwindowmanagerinterface.html#createFormWindow">createFormWindow</a>() function that enables you to create a new form window which you can add to the collection of form windows that the manager maintains, using the <a href="qdesignerformwindowmanagerinterface.html#addFormWindow">addFormWindow</a>() slot. It also provides the <a href="qdesignerformwindowmanagerinterface.html#formWindowCount">formWindowCount</a>() function returning the number of form windows currently under the manager's control, the <a href="qdesignerformwindowmanagerinterface.html#formWindow">formWindow</a>() function returning the form window associated with a given index, and the <a href="qdesignerformwindowmanagerinterface.html#activeFormWindow">activeFormWindow</a>() function returning the currently selected form window. The <a href="qdesignerformwindowmanagerinterface.html#removeFormWindow">removeFormWindow</a>() slot allows you to reduce the number of form windows the manager must maintain, and the <a href="qdesignerformwindowmanagerinterface.html#setActiveFormWindow">setActiveFormWindow</a>() slot allows you to change the form window focus in <i>Qt Designer</i>'s workspace.</p>
<p>In addition, QDesignerFormWindowManagerInterface contains a collection of functions that enables you to intervene and control <i>Qt Designer</i>'s form editing actions. All these functions return the original action, making it possible to propagate the function further after intervention.</p>
<p>Finally, the interface provides three signals which are emitted when a form window is added, when the currently selected form window changes, or when a form window is removed, respectively. All the signals carry the form window in question as their parameter.</p>
